Hence, the coal ash content should be maintained reasonably constant preferably to within about +1- 2%. High ash coals, up to 35 or 40% ash content, can be used in cement kilns provided that the ash content is controlled. For coals above about 15% ash content a stockpile-reclaim blending system is usually required.

In coal preparation, screening machines serve two purposes: sizing and media recovery. Oftentimes, the initial screening is performed by a scalping screen located outside the plant. This prevents the screens inside the plant from becoming overloaded. The deslime screens make the next cut and most prep plants size to minus 1 mm.

A coal-blending model has been developed using relationships between coal and coke quality parameters. This coal-blending model gives a least-cost coal blend for the desired coal blend quality in terms of ash, volatile matter, mean maximum reflectance, and coke quality based on the coke strength and ash content. The model takes into account …
